TABLE-FAN.

Application filed November To all whom it may concern:

Be it known that I, JAMES A. F owLnn, a citizen of the United States,residing at Glenallen, in the county of Bollinger and State of Missouri,have invented certain new and useful Improvements in Table-Fans, ofwhich the following is a specification.

This invention relates to tables and is designed more particularly toprovide a contrally disposed rotating fan, said fan being adapted tocool the atmosphere surrounding the table and drive all insects from theimmediate locality thereof.

Among other objects this invention is constructed in such a manner thatit may be operated by the foot of one of the occupants of the table withlittle or no exertion.

With the above and other objects in view this invention consists in theconstruction, combination, and arrangement of parts all as hereinaftermore fully described, specifically claimed, and illustrated in theaccompanying drawings, in which:

Figure 1 is a vertical section of a table provided with my improved fan;Fig. 2 is a plan view of the fan showing the means whereby the same issecured to the fan shaft; Fig. 3 is a detail perspective view of thetreadle, link, and pitman; Fig. 4 is a sectional view of the ball andsocket, Fig. 5 is a plan view of the bracket, and Fig. 6 is a sideelevation partly in section of a modified form of the means for securingthe fan to the shaft.

The main body portion of the present invention comprises a table of anyconstruction having the top 1 and the legs 2, the top being providedwith a centrally disposed orifice 3. A bracket 4 is carried on the undersurface of the table top and is so constructed that it is looselyprovided with a series of angularly bent legs or supports 5 crossingeach other at right angles and having a plate 6 riveted thereto at thejunction of said supports 5, said supports and plate being pierced bythe centrally disposed opening 8.

A vertical fan shaft 7 passes through the registering openings 3 and 8in the table and bracket respectively and is retained therein by thebearing plate 9 secured thereto above the plate 6 of the bracket. Acrank 10 is formed on the lower extremity of said shaft and has securedthereto a pitman 11, said pitman being retained on the crank by means ofa nut and bearing plate 12 and 13 threaded on the outer terminalthereof. A

socket comprising a pair of spring plates 14L having recesses formedtherein is secured to the outer extremity of the pitman 11. A clampingscrew 15 is disposed between the pitman and the recesses piercing theplates in such a manner that the same may be converged or diverged byadjustin the tension of the same. A treadlc hanger 17 is secured to oneof the legs 2 of the table and has a portion 18 bent laterally to whichis pivotally secured a treadle 19. A link connection 20 is providedbetween the pitman 11 and the treadle, said connection having a ball 21formed on its upper extremity adapted to be pivotally engaged in therecesses 16 between the plates 14: and being riveted at its oppositeextremity to the treadle. A bearing 22 is provided in the orifice 3 ofthe table to prevent any wear upon the table and retain the shaft in arigid position.

The fan comprises the blades 23 having the circular connecting members2% engag ing each side thereof and secured thereto by rivets 25. A pairof longitudinally extending strips 26 interposed between the blades and.secured between the connecting members adjacent said blades by therivets 27 are provided with a centrally disposed vertical opening 28 inwhich the shaft 7 is received; said shaft being retained between theplates by a rivet or screw 29 in one side thereof and the clainpii'lgbolt 30 on the other side of the shaft and in this manner devises ameans whereby the vertical adjustment of the fan upon the shaft may beobtained. A cap 31 is threaded on the upper extremity of the shaft topresent a finished appearance of the same.

It will readily be seen that upon applying power to the treadle 19 thepitman 1.1 will be reciprocatcd and as a result rotate the crank andshaft 10 and 7 respectively consequently rotating the fan.

The modification illustrated in Fig. 6 of the annexed drawings comprisesan approximately elliptical frame having at each extremity of itstransverse axis an interiorly longitudinal axis an opening 32. The shaft7 is adapted to pass through the openings 32 and is retained therein byset screws 33 operating in the sides of said openings.

34L, the outer extremity of each of which is reduced and threaded andadapted to be threaded opening 35, and at each end of its The fans 23are provided with the shanks received in one of the threaded openings 35of the frame 37.

Having thus fully described the invention What I claim as new and desireto secure by Letters Patent is l. A device of the class described,comprising a table, a bracket secured on the under face of said table,said bracket and table having registering openings formed therein, avertical fan shaft rotatably mounted in said openings and provided withbearing plates adjacent said bracket, a crank formed at the lowerextremity of said fan shaft, said crank being connected by a pitlnan andlink to a treadle supported by a hanger on one of the legs of the table,and a fan secured to the upper extremity of said shaft comprising aplurality of blades connected together by semi-circular bands, saidbands having clamping strips disposed therebetween, and means wherebysaid clamp ing strips may be adjusted to engage said shaft.

2. A device of the class described c0mprising, in combination, a table,a shaft rotatably mounted in said table, means for rotating said shaft,and a fan secured to the upper extremity of said shaft comprising aplurality of blades secured together by clamping bands, each of saidbands extending'semi-circularly about said shaft, and clamping stripsinterposed between said bands, said clamping strips being rigidlysecured on one side of said shaft and provided with atransverseadjustment on the other side.

In testimony whereof I aflix my signature in presence of two witnesses.
